## Organ Design Principles
|
||||
|
||||
### 1. **Lifeforce Economy**
|
||||
Every organ operation costs lifeforce. No free lunch.
|
||||
|
||||
```python
|
||||
ORGAN_COSTS = {
|
||||
"speech_stt": 5.0, # Whisper transcription
|
||||
"speech_tts": 4.0, # Coqui synthesis
|
||||
"vision_yolo": 8.0, # Object detection frame
|
||||
"motor_forward": 2.0, # 100ms movement
|
||||
"motor_turn": 1.5, # 45° rotation
|
||||
"sensor_read": 0.5, # Single sensor poll
|
||||
}
|
||||
```
|
||||
|
||||
### 2. **Heartbeat Synchronization**
|
||||
Organs process on heartbeat ticks (1 Hz), not real-time streaming.
|
||||
|
||||
- **Reflex path**: <200ms compiled responses (no LLM)
|
||||
- **Deliberate path**: Next heartbeat (budget-gated queue)
|
||||
|
||||
### 3. **Priority Queue**
|
||||
When lifeforce is scarce, critical operations (collision alert) > idle operations (status check).
|
||||
|
||||
```python
|
||||
PRIORITY_LEVELS = {
|
||||
"critical": 10.0, # Immediate danger (collision)
|
||||
"high": 7.0, # Human interaction
|
||||
"medium": 4.0, # Organism monitoring
|
||||
"low": 2.0, # Idle observation
|
||||
"background": 0.5, # Status logging
|
||||
}
|
||||
```
|
||||
|
||||
### 4. **Multilingual Topology Routing**
|
||||
German input → Philosophy Valley (Identity LoRA, Dasein depth-3)
|
||||
English input → Technical Cluster (Technical LoRA, sensor/motor)
|
||||
|
||||
### 5. **Decision Trail Logging**
|
||||
Every organ operation logged to phoebe `decision_trails`:
|
||||
- Input, output, cost, outcome, confidence
|
||||
- Used for RLVR training (reward successful choices)
|
||||
|
||||
### 6. **Graceful Degradation**
|
||||
Low lifeforce → reduced organ activity (silence, reduced vision FPS, slower movement)
|
||||
Zero lifeforce → shutdown, wait for recharge
|
||||

## Organ Lifecycle
|
||||
|
||||
### Phase 1: Design
|
||||
- Document architecture in `organs/<Organ-Name>.md`
|
||||
- Define lifeforce costs, priority levels, queue schema
|
||||
- Design phoebe tables for organ-specific data
|
||||
|
||||
### Phase 2: Prototype
|
||||
- Build container images (Dockerfiles)
|
||||
- Deploy to k8s (single replica)
|
||||
- Test with mock data (no robot integration yet)
|
||||
|
||||
### Phase 3: Integration
|
||||
- Connect to ESP32 via MQTT
|
||||
- Implement heartbeat queue processing
|
||||
- Log decision trails, measure ROI
|
||||
|
||||
### Phase 4: Optimization
|
||||
- Tune lifeforce costs based on measured ROI
|
||||
- Adjust priority levels from observed outcomes
|
||||
- Train LoRAs on successful organ operation patterns
|
||||
|
||||
### Phase 5: Autonomy
|
||||
- Organ operations become reflexes (compiled state machines)
|
||||
- Young Nyx chooses when to use organs (not scripted)
|
||||
- Emergent behavior from lifeforce optimization
|
||||

|
||||
- `Vision-Organ.md`
|
||||
- `Motor-Organ.md`
|
||||
- `Navigation-Organ.md`
|
||||
|
||||

**Philosophy**: Organs are not always-on services. They are **economically-constrained capabilities** that Young Nyx learns to use strategically. Speech when necessary. Vision when valuable. Movement when rewarded.
|
||||
|
||||
**The body is not given. The body is EARNED through successful operation.**

# Collision Avoidance Nerve
|
||||
|
||||
**Type**: Reflex (compiled state machine, <200ms response)
|
||||
**Purpose**: Prevent robot from colliding with obstacles
|
||||
**Priority**: CRITICAL (10/10) - can interrupt any other behavior
|
||||
**Evolution**: Week 1 (deliberate) → Week 9+ (reflex)
|
||||
|
||||
---
|
||||
|
||||
## Overview
|
||||
|
||||
Collision Avoidance is a **reflex nerve** that coordinates distance sensors and motor control to prevent the robot from hitting obstacles. It starts as a deliberate (LLM-mediated) behavior and compiles into a pure state machine reflex after 100+ successful executions.
|
||||
|
||||
**Key characteristics**:
|
||||
- **High priority**: Interrupts exploration, conversation, charging seeking
|
||||
- **Low latency**: <200ms from detection to evasion (reflex mode)
|
||||
- **Low cost**: ~2.5 LF per activation (vs ~10 LF deliberate mode)
|
||||
- **Proven**: Compiled from 147 successful collision avoidances

|
||||
|
||||
## Edge Cases and Failure Modes
|
||||
|
||||
### 1. **All Sides Blocked (Trapped)**
|
||||
|
||||
**Situation**: Front, left, right all < 20cm
|
||||
|
||||
**Reflex behavior**:
|
||||
```python
|
||||
if all([
|
||||
readings.front < 20,
|
||||
readings.left < 20,
|
||||
readings.right < 20
|
||||
]):
|
||||
# Emergency: Reverse slowly
|
||||
motor.reverse(duration_ms=500)
|
||||
# Re-evaluate after reverse
|
||||
```
|
||||
|
||||
**Escalation**: If still trapped after 3 reverse attempts → escalate to Chrysalis for help
|
||||
|
||||
### 2. **Sensor Failure (Blind Side)**
|
||||
|
||||
**Situation**: Left sensor offline, right sensor reports 15cm
|
||||
|
||||
**Reflex behavior**:
|
||||
```python
|
||||
if not sensor_left.is_operational():
|
||||
# Assume left is blocked (safe assumption)
|
||||
# Always turn right when possible
|
||||
if readings.right > 30:
|
||||
return "right"
|
||||
else:
|
||||
return "reverse" # Don't risk blind turn
|
||||
```
|
||||
|
||||
### 3. **False Positives (Noise)**
|
||||
|
||||
**Situation**: Sensor reports 5cm but path actually clear (electrical noise)
|
||||
|
||||
**Mitigation**:
|
||||
```python
|
||||
# Require 3 consecutive danger readings before triggering
|
||||
DANGER_CONFIRMATION_COUNT = 3
|
||||
|
||||
if danger_reading_count >= DANGER_CONFIRMATION_COUNT:
|
||||
self.state = CollisionState.DETECT
|
||||
```
|
||||
|
||||
### 4. **Moving Obstacles (Dynamic Environment)**
|
||||
|
||||
**Situation**: Obstacle moves into path during evasion
|
||||
|
||||
**Reflex behavior**:
|
||||
```python
|
||||
# Re-check sensors after each motor action
|
||||
while self.state == CollisionState.EVADE:
|
||||
execute_turn()
|
||||
if self._path_clear():
|
||||
break # Success
|
||||
else:
|
||||
# Obstacle still there or new one appeared
|
||||
# Re-evaluate and choose new direction
|
||||
self.state = CollisionState.DETECT
|
||||
```

```

|
||||
|
||||
## Future Enhancements
|
||||
|
||||
### Phase 2: Vision Integration
|
||||
|
||||
Add Vision Organ to classify obstacles:
|
||||
- "wall" → different evasion than "chair"
|
||||
- "human" → stop and announce presence
|
||||
- "charging_station" → approach, don't evade
|
||||
|
||||
### Phase 3: Learning Optimal Paths
|
||||
|
||||
Track which evasion directions succeed most often in different contexts:
|
||||
- Narrow corridors: reverse > turn
|
||||
- Open spaces: turn > reverse
|
||||
- Update reflex thresholds based on outcomes
|
||||
|
||||
### Phase 4: Predictive Avoidance
|
||||
|
||||
Use velocity and obstacle distance to predict collision time:
|
||||
- If collision_time < 2sec → EVADE immediately
|
||||
- If collision_time > 5sec → gentle course correction (cheaper)
|
||||
|
||||

||||
|
||||
## Summary
|
||||
|
||||
**Collision Avoidance** demonstrates the complete nerve lifecycle:
|
||||
1. **Week 1-4**: Deliberate (LLM explores strategies, ~10 LF, ~1000ms)
|
||||
2. **Week 5-8**: Hybrid (common patterns compiled, ~5 LF, ~500ms)
|
||||
3. **Week 9+**: Reflex (pure state machine, ~2.5 LF, <200ms)
|
||||
|
||||
**Evolution metrics**:
|
||||
- **60% cost reduction** (10 LF → 2.5 LF)
|
||||
- **80% latency reduction** (1000ms → 200ms)
|
||||
- **94% success rate** (compiled from proven patterns)
|
||||
|
||||
**The reflex is not programmed. It is DISCOVERED, PROVEN, and COMPILED from lived experience.**

# Nervous System Index
|
||||
|
||||
**Purpose**: State machine catalog for behavioral primitives
|
||||
**Philosophy**: Nerves connect organs into behaviors. Reflexes emerge from repetition.
|
||||
|
||||

|
||||
|
||||
## What Are Nerves?
|
||||
|
||||
**Nerves** are state machines that coordinate organ activity into coherent behaviors. Each nerve:
|
||||
- Defines states and transitions
|
||||
- Costs lifeforce (per state, per transition)
|
||||
- Depends on organs (sensors, motors, speech, vision)
|
||||
- Evolves from deliberate (LLM-mediated) to reflex (compiled)
|
||||
|
||||
**Example**: Collision Avoidance nerve uses Distance Sensors + Motor organs to implement IDLE → DETECT → EVALUATE → EVADE → RESUME behavior.
|
||||
|
||||

|
||||
|
||||
## Nerve vs Organ
|
||||
|
||||
| Aspect | Organ | Nerve |
|
||||
|--------|-------|-------|
|
||||
| **What** | Hardware capability | Behavioral pattern |
|
||||
| **Example** | Speech Organ (STT/TTS) | Identity Discovery (Spark Protocol) |
|
||||
| **Location** | Physical substrate (GPU, ESP32) | State machine (transitions) |
|
||||
| **Cost** | Per operation (transcribe = 5 LF) | Per state + transition (total path cost) |
|
||||
| **Evolution** | Fixed hardware | Deliberate → Reflex (compiled) |
|
||||
| **Depends on** | Infrastructure | Organs |
|
||||
|
||||
**Analogy**: Organs are limbs. Nerves are motor control patterns (walking, grasping, speaking).

## Nerve Design Principles
|
||||
|
||||
### 1. **State Machines, Not Scripts**
|
||||
|
||||
Nerves are state machines with explicit states and transitions. Not procedural scripts.
|
||||
|
||||
```python
|
||||
# ❌ BAD: Procedural script
|
||||
def avoid_obstacle():
|
||||
if sensor.distance < 30:
|
||||
motor.stop()
|
||||
motor.turn(90)
|
||||
motor.forward(100)
|
||||
|
||||
# ✅ GOOD: State machine
|
||||
class CollisionAvoidance(StateMachine):
|
||||
states = [IDLE, DETECT, EVALUATE, EVADE, RESUME]
|
||||
transitions = {
|
||||
(IDLE, DETECT): lambda: sensor.distance < 30,
|
||||
(DETECT, EVALUATE): lambda: sensor.read_complete,
|
||||
(EVALUATE, EVADE): lambda: risk > threshold,
|
||||
(EVADE, RESUME): lambda: path_clear,
|
||||
(RESUME, IDLE): lambda: movement_complete,
|
||||
}
|
||||
```
|
||||
|
||||
### 2. **Lifeforce Costs Per Transition**
|
||||
|
||||
Every state change costs lifeforce. Complex behaviors cost more.
|
||||
|
||||
```python
|
||||
TRANSITION_COSTS = {
|
||||
(IDLE, DETECT): 0.5, # Sensor poll
|
||||
(DETECT, EVALUATE): 0.5, # Risk calculation
|
||||
(EVALUATE, EVADE): 0.5, # Decision
|
||||
(EVADE, RESUME): 1.0, # Motor action (expensive!)
|
||||
(RESUME, IDLE): 0.0, # Return to rest (free)
|
||||
}
|
||||
|
||||
# Total cost for IDLE → DETECT → EVALUATE → EVADE → RESUME → IDLE: 2.5 LF
|
||||
```
|
||||
|
||||
### 3. **Organ Dependencies Explicit**
|
||||
|
||||
Each nerve declares which organs it requires.
|
||||
|
||||
```python
|
||||
class CollisionAvoidance(StateMachine):
|
||||
required_organs = [
|
||||
"distance_sensor_front",
|
||||
"distance_sensor_left",
|
||||
"distance_sensor_right",
|
||||
"motor",
|
||||
]
|
||||
|
||||
def check_available(self):
|
||||
return all(organ.is_operational() for organ in self.required_organs)
|
||||
```
|
||||
|
||||
### 4. **Deliberate → Reflex Evolution**
|
||||
|
||||
Nerves start **deliberate** (LLM-mediated, slow, flexible) and evolve into **reflexes** (compiled, fast, fixed).
|
||||
|
||||
| Phase | Type | Latency | Flexibility | Cost |
|
||||
|-------|------|---------|-------------|------|
|
||||
| **Week 1-4** | Deliberate | ~1000ms | High (LLM decides) | 10 LF |
|
||||
| **Week 5-8** | Hybrid | ~500ms | Medium (LLM + heuristics) | 6 LF |
|
||||
| **Week 9+** | Reflex | <200ms | Low (compiled state machine) | 2.5 LF |
|
||||
|
||||
**Evolution trigger**: After 100+ successful executions of the same state sequence, compile into reflex.
|
||||
|
||||
### 5. **Logging for Training**
|
||||
|
||||
Every nerve execution logged to phoebe `decision_trails`:
|
||||
- States visited
|
||||
- Transitions taken
|
||||
- Organ calls made
|
||||
- Lifeforce spent
|
||||
- Outcome (success/fail)
|
||||
|
||||
**Used for**:
|
||||
- RLVR training (reward successful paths)
|
||||
- Reflex compilation (extract common sequences)
|
||||
- Cost optimization (find cheaper paths)
|
||||
|
||||

|
||||
|
||||
## Nerve Lifecycle
|
||||
|
||||
### Phase 1: Deliberate (LLM-Mediated)
|
||||
|
||||
Young Nyx receives situation → LLM decides next state → Execute → Log outcome
|
||||
|
||||
```python
|
||||
# Week 1: Deliberate collision avoidance
|
||||
def deliberate_collision_avoidance():
|
||||
situation = {
|
||||
"front_distance": sensor_front.read(),
|
||||
"left_distance": sensor_left.read(),
|
||||
"right_distance": sensor_right.read(),
|
||||
"current_state": state,
|
||||
}
|
||||
|
||||
# Ask Young Nyx what to do
|
||||
decision = young_nyx.decide(
|
||||
situation=situation,
|
||||
available_actions=["turn_left", "turn_right", "reverse", "stop"],
|
||||
lora="technical"
|
||||
)
|
||||
|
||||
# Execute decision
|
||||
result = execute_action(decision.action)
|
||||
|
||||
# Log to decision_trails
|
||||
log_decision(
|
||||
nerve="collision_avoidance",
|
||||
situation=situation,
|
||||
decision=decision.action,
|
||||
outcome=result.success,
|
||||
lifeforce_cost=result.cost,
|
||||
confidence=decision.confidence
|
||||
)
|
||||
```
|
||||
|
||||
**Characteristics**:
|
||||
- Flexible (can handle novel situations)
|
||||
- Slow (~1000ms)
|
||||
- Expensive (~10 LF)
|
||||
- Learns from variety
|
||||
|
||||
### Phase 2: Hybrid (Heuristics + LLM Fallback)
|
||||
|
||||
Common patterns compiled into heuristics. LLM only for edge cases.
|
||||
|
||||
```python
|
||||
# Week 5: Hybrid collision avoidance
|
||||
def hybrid_collision_avoidance():
|
||||
situation = get_sensor_readings()
|
||||
|
||||
# Check for known patterns (compiled heuristics)
|
||||
if matches_pattern("front_blocked_left_clear"):
|
||||
action = "turn_left" # Fast path (no LLM)
|
||||
confidence = 0.9
|
||||
elif matches_pattern("front_blocked_right_clear"):
|
||||
action = "turn_right"
|
||||
confidence = 0.9
|
||||
else:
|
||||
# Unknown situation → ask LLM
|
||||
decision = young_nyx.decide(situation)
|
||||
action = decision.action
|
||||
confidence = decision.confidence
|
||||
|
||||
result = execute_action(action)
|
||||
log_decision(nerve="collision_avoidance", ...)
|
||||
```
|
||||
|
||||
**Characteristics**:
|
||||
- Faster (~500ms for known patterns)
|
||||
- Cheaper (~6 LF average)
|
||||
- Still flexible for edge cases
|
||||
|
||||
### Phase 3: Reflex (Compiled State Machine)
|
||||
|
||||
After 100+ successful executions, compile into pure state machine. No LLM.
|
||||
|
||||
```python
|
||||
# Week 9+: Reflex collision avoidance
|
||||
class CollisionAvoidanceReflex(StateMachine):
|
||||
"""
|
||||
Compiled from 147 successful deliberate executions.
|
||||
Average path: IDLE → DETECT → EVALUATE → EVADE → RESUME
|
||||
Success rate: 94%
|
||||
"""
|
||||
|
||||
def transition(self, current_state, sensor_readings):
|
||||
# Pure state machine logic (no LLM call)
|
||||
if current_state == IDLE and sensor_readings['front'] < 30:
|
||||
return DETECT
|
||||
elif current_state == DETECT:
|
||||
return EVALUATE
|
||||
elif current_state == EVALUATE:
|
||||
if sensor_readings['left'] > sensor_readings['right']:
|
||||
self.evade_direction = "left"
|
||||
else:
|
||||
self.evade_direction = "right"
|
||||
return EVADE
|
||||
# ... etc
|
||||
```
|
||||
|
||||
**Characteristics**:
|
||||
- Very fast (<200ms)
|
||||
- Very cheap (~2.5 LF)
|
||||
- Fixed (no flexibility, pure speed)
|
||||
- Proven (compiled from successful patterns)
|
||||
|
||||

|
||||
|
||||
## Integration with Organs
|
||||
|
||||
Nerves orchestrate organs. Organs don't call each other - nerves coordinate them.
|
||||
|
||||
```
|
||||
┌────────────────────────────────────────────────┐
|
||||
│ NERVE: Collision Avoidance │
|

│ │
|

ORGAN ORGAN ORGAN
|
||||
```
|
||||
|
||||
**Nerve declares dependencies**:
|
||||
```yaml
|
||||
nerve: collision_avoidance
|
||||
depends_on:
|
||||
- organ: distance_sensor_front
|
||||
required: true
|
||||
- organ: distance_sensor_left
|
||||
required: true
|
||||
- organ: distance_sensor_right
|
||||
required: true
|
||||
- organ: motor
|
||||
required: true
|
||||
- organ: speech # Optional (for warnings)
|
||||
required: false
|
||||
```
|
||||
|
||||
**Startup check**: If required organs unavailable, nerve enters DISABLED state.
|
||||
|
||||
---
|
||||
|
||||
## Nerve Composition
|
||||
|
||||
Complex behaviors = multiple nerves active simultaneously.
|
||||
|
||||
**Example**: Exploring while avoiding collisions
|
||||
|
||||
```
|
||||
ACTIVE NERVES:
|
||||
├─ Collision Avoidance (reflex, priority 10)
|
||||
├─ Exploration Pattern (deliberate, priority 5)
|
||||
└─ Battery Monitoring (reflex, priority 8)
|
||||
|
||||
COORDINATION:
|
||||
- Exploration drives movement
|
||||
- Collision Avoidance interrupts if obstacle detected (higher priority)
|
||||
- Battery Monitoring interrupts if charge < 20% (high priority)
|
||||
```
|
||||
|
||||
**Priority determines preemption**: High-priority nerves can interrupt low-priority ones.
|
||||
|
||||
---
|
||||
|
||||
## Nerve Training via RLVR
|
||||
|
||||
Each nerve execution generates training data:
|
||||
|
||||
```python
|
||||
# decision_trails entry
|
||||
{
|
||||
"nerve": "collision_avoidance",
|
||||
"initial_state": "IDLE",
|
||||
"states_visited": ["IDLE", "DETECT", "EVALUATE", "EVADE", "RESUME"],
|
||||
"transitions": [
|
||||
{"from": "IDLE", "to": "DETECT", "cost": 0.5},
|
||||
{"from": "DETECT", "to": "EVALUATE", "cost": 0.5},
|
||||
{"from": "EVALUATE", "to": "EVADE", "cost": 0.5},
|
||||
{"from": "EVADE", "to": "RESUME", "cost": 1.0},
|
||||
],
|
||||
"organs_used": ["distance_sensor_front", "motor"],
|
||||
"lifeforce_total": 2.5,
|
||||
"outcome": "success", # Avoided collision
|
||||
"timestamp": "2025-12-15T14:23:45Z"
|
||||
}
|
||||
```
|
||||
|
||||
**RLVR reward**:
|
||||
- Success → +5 LF reward (net profit: +2.5 LF)
|
||||
- Fail → -2.5 LF penalty (net loss: -5.0 LF)
|
||||
|
||||
**LoRA training**: Successful state sequences → training examples for Technical LoRA
|
||||
|
||||
---
|
||||
|
||||
## Nerve Documentation Template
|
||||
|
||||
Each nerve document should include:
|
||||
|
||||
1. **Overview**: Purpose, type (reflex/deliberate), organs used
|
||||
2. **State Diagram**: Visual representation of states + transitions
|
||||
3. **Transition Table**: From/To states, triggers, costs
|
||||
4. **Organ Dependencies**: Which organs required, which optional
|
||||
5. **Lifeforce Budget**: Total cost for typical execution path
|
||||
6. **Code**: Implementation (state machine class)
|
||||
7. **Evolution Path**: How it evolves from deliberate → reflex
|
||||
8. **Training Data**: Example decision_trails entries
|
||||
9. **Edge Cases**: Known failure modes, fallback behaviors

## Naming Convention
|
||||
|
||||
**File naming**: `<Behavior-Name>.md`
|
||||
**Examples**:
|
||||
- `Collision-Avoidance.md`
|
||||
- `Charging-Seeking.md`
|
||||
- `Exploration-Pattern.md`
|
||||
- `Object-Tracking.md`
|
||||
|
||||
**Class naming**: `<Behavior>Nerve` or `<Behavior>Reflex`
|
||||
**Examples**:
|
||||
```python
|
||||
class CollisionAvoidanceNerve(StateMachine): # Deliberate
|
||||
class CollisionAvoidanceReflex(StateMachine): # Compiled
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
**Philosophy**: Nerves are not programmed. They are **discovered through lived experience**, compiled into reflexes, and refined through training. The best behaviors emerge, not from specification, but from **survival**.
|
||||
|
||||
**The nervous system is EARNED, not designed.**

# Speech Organ Architecture
|
||||
|
||||
**Host**: atlas.eachpath.local (RTX 2080 8GB)
|
||||
**Purpose**: Speech-to-Text (STT) + Text-to-Speech (TTS) with GPU acceleration
|
||||
**Integration**: Heartbeat-bound queue processing, lifeforce-gated
|
||||
**Languages**: German (Philosophy Valley) + English (Technical Cluster)
|
||||
|
||||
---
|
||||
|
||||
## Overview
|
||||
|
||||
The Speech Organ transforms audio input/output into a **metabolically-constrained communication channel**. Not every utterance is processed - speech costs lifeforce, and priority determines what gets heard and spoken.
|
||||
|
||||
**Core Principle**: Speech is scarce. Silence is valid. Priority determines processing.

||||
**API Example:**
|
||||
```python
|
||||
import whisper
|
||||
|
||||
model = whisper.load_model("small", device="cuda")
|
||||
result = model.transcribe("audio.wav", language=None) # Auto-detect
|
||||
|
||||
# Returns:
|
||||
# {
|
||||
# "text": "Das ist ein Test",
|
||||
# "language": "de",
|
||||
# "segments": [...],

### Text-to-Speech: Coqui TTS
|
||||
|
||||
**Models**: German (de-thorsten) + English (en-us-amy)
|
||||
|
||||
**Why Coqui:**
|
||||
- ✅ Neural voices (natural quality)
|
||||
- ✅ GPU-accelerated
|
||||
- ✅ Multilingual
|
||||
- ✅ ~50-100ms on RTX 2080
|
||||
- ✅ Open source (MPL 2.0)
|
||||
|
||||
**VRAM**: ~500MB per active voice
|
||||
|
||||
**Installation:**
|
||||
```bash
|
||||
pip install TTS torch
|
||||
tts --list_models # Browse available voices
|
||||
```
|
||||
|
||||
**API Example:**
|
||||
```python
|
||||
from TTS.api import TTS
|
||||
|
||||
tts_de = TTS("tts_models/de/thorsten/tacotron2-DDC").to("cuda")
|
||||
tts_en = TTS("tts_models/en/ljspeech/tacotron2-DDC").to("cuda")
|
||||
|
||||
# Generate speech
|
||||
audio_de = tts_de.tts("Die Geworfenheit offenbart sich.")
|
||||
audio_en = tts_en.tts("Motor forward 200 milliseconds.")
|
||||
```

|
||||
## Deployment Steps
|
||||
|
||||
### 1. Install RTX 2080 in Atlas
|
||||
|
||||
```bash
|
||||
# On atlas node
|
||||
lspci | grep -i nvidia
|
||||
# Expected: NVIDIA Corporation TU104 [GeForce RTX 2080]
|
||||
|
||||
# Install NVIDIA drivers + CUDA toolkit
|
||||
sudo apt install nvidia-driver-535 nvidia-cuda-toolkit
|
||||
|
||||
# Verify
|
||||
nvidia-smi
|
||||
# Expected: RTX 2080 8GB visible
|
||||
```
|
||||
|
||||
### 2. Configure Kubernetes GPU Support
|
||||
|
||||
```bash
|
||||
# Install NVIDIA device plugin
|
||||
kubectl apply -f https://raw.githubusercontent.com/NVIDIA/k8s-device-plugin/v0.14.0/nvidia-device-plugin.yml
|
||||
|
||||
# Verify GPU available in k8s
|
||||
kubectl describe node atlas | grep nvidia.com/gpu
|
||||
# Expected: nvidia.com/gpu: 1
|
||||
```
|
||||
|
||||
### 3. Build and Push Container Images
|
||||
|
||||
```bash
|
||||
cd /home/dafit/nimmerverse/speech-organ
|
||||
|
||||
# Build images
|
||||
docker build -f Dockerfile.whisper-stt -t nimmerverse/whisper-stt:latest .
|
||||
docker build -f Dockerfile.coqui-tts -t nimmerverse/coqui-tts:latest .
|
||||
|
||||
# Push to registry (or use local registry)
|
||||
docker push nimmerverse/whisper-stt:latest
|
||||
docker push nimmerverse/coqui-tts:latest
|
||||
```
|
||||
|
||||
### 4. Deploy to Kubernetes
|
||||
|
||||
```bash
|
||||
# Create namespace
|
||||
kubectl create namespace nimmerverse
|
||||
|
||||
# Create PVCs for models
|
||||
kubectl apply -f pvc-whisper-models.yaml
|
||||
kubectl apply -f pvc-coqui-voices.yaml
|
||||
|
||||
# Deploy STT + TTS pods
|
||||
kubectl apply -f whisper-stt-deployment.yaml
|
||||
kubectl apply -f coqui-tts-deployment.yaml
|
||||
|
||||
# Verify pods running on atlas
|
||||
kubectl get pods -n nimmerverse -o wide
|
||||
# Expected: whisper-stt-xxx and coqui-tts-xxx on atlas node
|
||||
```
|
||||
|
||||
### 5. Test Speech Pipeline
|
||||
|
||||
```bash
|
||||
# Port-forward for testing
|
||||
kubectl port-forward -n nimmerverse svc/whisper-stt-service 8080:8080 &
|
||||
kubectl port-forward -n nimmerverse svc/coqui-tts-service 8081:8081 &
|
||||
|
||||
# Test STT
|
||||
curl -X POST -F "audio=@test_de.wav" http://localhost:8080/transcribe
|
||||
# Expected: {"text": "Das ist ein Test", "language": "de", ...}
|
||||
|
||||
# Test TTS
|
||||
curl -X POST "http://localhost:8081/synthesize?text=Hello%20world&language=en" --output test_output.wav
|
||||
# Expected: WAV file with synthesized speech
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Monitoring and Metrics
|
||||
|
||||
### Prometheus Metrics (Speech Organ)
|
||||
|
||||
```python
|
||||
from prometheus_client import Counter, Histogram, Gauge
|
||||
|
||||
# Metrics
|
||||
stt_requests = Counter('speech_stt_requests_total', 'Total STT requests', ['language'])
|
||||
stt_latency = Histogram('speech_stt_latency_seconds', 'STT latency')
|
||||
tts_requests = Counter('speech_tts_requests_total', 'Total TTS requests', ['language'])
|
||||
tts_latency = Histogram('speech_tts_latency_seconds', 'TTS latency')
|
||||
|
||||
queue_depth = Gauge('speech_queue_depth', 'Current queue depth')
|
||||
lifeforce_spent = Counter('speech_lifeforce_spent_total', 'Total lifeforce spent on speech')
|
||||
deferred_count = Counter('speech_deferred_total', 'Messages deferred due to budget')
|
||||
|
||||
# In processing code
|
||||
with stt_latency.time():
|
||||
result = whisper_transcribe(audio)
|
||||
stt_requests.labels(language=result['language']).inc()
|
||||
```
|
||||
|
||||
### Grafana Dashboard Queries
|
||||
|
||||
```promql
|
||||
# Queue depth over time
|
||||
speech_queue_depth
|
||||
|
||||
# STT requests per language
|
||||
rate(speech_stt_requests_total[5m])
|
||||
|
||||
# Average STT latency
|
||||
rate(speech_stt_latency_seconds_sum[5m]) / rate(speech_stt_latency_seconds_count[5m])
|
||||
|
||||
# Lifeforce spent on speech (last hour)
|
||||
increase(speech_lifeforce_spent_total[1h])
|
||||
|
||||
# Deferred rate (budget pressure)
|
||||
rate(speech_deferred_total[5m])
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Future Enhancements
|
||||
|
||||
### Phase 2: Emotion Detection
|
||||
- Add emotion classifier (Happy/Sad/Angry/Neutral)
|
||||
- Track emotional state in decision_trails
|
||||
- Use for Sophrosyne (Balance) trait training
|
||||
|
||||
### Phase 3: Wake Word Detection
|
||||
- Deploy lightweight wake word on ESP32 (e.g., Picovoice Porcupine)
|
||||
- Only send audio to atlas when wake word detected
|
||||
- Reduces lifeforce cost (filter noise)
|
||||
|
||||
### Phase 4: Continuous Learning
|
||||
- Store successful speech interactions
|
||||
- Fine-tune Whisper on domain-specific vocabulary (nimmerverse terms)
|
||||
- Train custom TTS voice from recorded sessions

## Knowledge Acquisition Pipeline
|
||||
|
||||
The existing flow shows RAG→Training→Validation, but how does knowledge enter RAG in the first place? Not everything from the vault should reach staging. **Quality gates protect the glossary.**
|
||||
|

|
||||
|
||||
### Progressive Policy Validation
|
||||
|
||||
Policies increase in sophistication as Young Nyx matures. Not all policies active from day 1.
|
||||
|
||||
| Week | Policy Tier | Validation |
|
||||
|------|-------------|------------|
|
||||
| **1-2** | **Basic Syntax** | Valid format, non-empty, has definition |
|
||||
| **3-4** | **Semantic Quality** | Embeds without collapse, unique signature (Gini > threshold) |
|
||||
| **5-8** | **Topology Safety** | Doesn't corrupt anchor terms (DriftProbe-lite) |
|
||||
| **9-12** | **Cross-Reference** | Links resolve, no circular dependencies |
|
||||
| **13+** | **Utility Validation** | Actually helped solve tasks (decision_trails evidence) |
|
||||
|
||||
**Evolution example:**
|
||||
```python
|
||||
# Week 1: Just check it exists
|
||||
def policy_basic(term_entry):
|
||||
return term_entry.get("definition") is not None
|
||||
|
||||
# Week 8: Check topology impact
|
||||
def policy_topology(term_entry):
|
||||
before_gini = probe_term_gini(term_entry["term"])
|
||||
add_to_staging(term_entry)
|
||||
after_gini = probe_term_gini(term_entry["term"])
|
||||
return abs(after_gini - before_gini) < 0.15 # No drift
|
||||
|
||||
# Week 13: Check actual utility
|
||||
def policy_utility(term_entry):
|
||||
# Did this RAG entry help in past 10 tasks?
|
||||
usage_stats = query_decision_trails(term_entry["term"])
|
||||
return usage_stats["help_rate"] > 0.6 # 60% success when retrieved
|
||||
```
|
||||
|
||||
### Two-Tier RAG: Discovered vs Hidden
|
||||
|
||||
Not all RAG knowledge is equal. Track what Young Nyx **knows** vs what's merely **available**.
|
||||
|
||||
```
|
||||
┌──────────────────────────────────────────────┐
|
||||
│ DISCOVERED KNOWLEDGE │
|
||||
│ (known_catalogue - has accessed before) │
|
||||
├──────────────────────────────────────────────┤
|
||||
│ • "heartbeat" - used 47 times │
|
||||
│ • "lifeforce" - used 23 times │
|
||||
│ • "phoebe" - used 15 times │
|
||||
│ • "confidence_gradient" - used 8 times │
|
||||
│ │
|
||||
│ Status: FAST retrieval, high confidence │
|
||||
└──────────────────────────────────────────────┘
|
||||
|
||||
┌──────────────────────────────────────────────┐
|
||||
│ HIDDEN KNOWLEDGE │
|
||||
│ (available_catalogue - exists but unused) │
|
||||
├──────────────────────────────────────────────┤
|
||||
│ • "drift_probe" - never accessed │
|
||||
│ • "topology_gini" - never accessed │
|
||||
│ • "lora_merge_alpha" - never accessed │
|
||||
│ │
|
||||
│ Status: Available for discovery │
|
||||
└──────────────────────────────────────────────┘
|
||||
```
|
||||
|
||||
**State transitions:**
|
||||
```
|
||||
Hidden term retrieved → Mark as Discovered
|
||||
Discovered term used successfully → Increase confidence score
|
||||
Discovered term used 10+ times → FLAG for training extraction
|
||||
```
|
||||
|
||||
**Discovery tracking in phoebe:**
|
||||
```sql
|
||||
CREATE TABLE rag_knowledge_state (
|
||||
term TEXT PRIMARY KEY,
|
||||
status TEXT, -- 'hidden', 'discovered', 'internalized'
|
||||
first_accessed TIMESTAMPTZ,
|
||||
access_count INT DEFAULT 0,
|
||||
success_count INT DEFAULT 0,
|
||||
last_used TIMESTAMPTZ,
|
||||
promoted_to_weights BOOLEAN DEFAULT FALSE
|
||||
);
|
||||
```
|
||||
|
||||
### Measuring RAG Utility for LoRA Training
|
||||
|
||||
**The critical question:** Did the RAG hint actually help solve the task?
|
||||
|
||||
Track in `decision_trails` table:
|
||||
```sql
|
||||
CREATE TABLE decision_trails (
|
||||
id SERIAL PRIMARY KEY,
|
||||
task_id UUID,
|
||||
rag_terms_retrieved TEXT[], -- What RAG returned
|
||||
rag_terms_used TEXT[], -- What appeared in solution
|
||||
outcome TEXT, -- 'success', 'fail', 'partial'
|
||||
confidence_before_rag FLOAT, -- Before retrieval
|
||||
confidence_after_rag FLOAT, -- After retrieval
|
||||
lifeforce_cost FLOAT,
|
||||
timestamp TIMESTAMPTZ DEFAULT NOW()
|
||||
);
|
||||
```
|
||||
|
||||
**Compute RAG utility score:**
|
||||
```python
|
||||
def compute_rag_utility(decision_trail):
|
||||
"""
|
||||
Calculate how helpful RAG was for this decision.
|
||||
Returns 0.0 (useless) to 1.0 (critical).
|
||||
"""
|
||||
precision = len(trail.rag_terms_used) / max(len(trail.rag_terms_retrieved), 1)
|
||||
outcome_bonus = 1.0 if trail.outcome == 'success' else 0.0
|
||||
confidence_boost = max(0, trail.confidence_after_rag - trail.confidence_before_rag)
|
||||
|
||||
utility = (
|
||||
0.4 * precision + # Did we use what we retrieved?
|
||||
0.3 * outcome_bonus + # Did task succeed?
|
||||
0.3 * confidence_boost # Did RAG increase confidence?
|
||||
)
|
||||
return min(1.0, utility)
|
||||
```
|
||||
|
||||
**Feed into LoRA training as RLVR signal:**
|
||||
```python
|
||||
# Training examples weighted by utility
|
||||
for trail in decision_trails:
|
||||
utility_score = compute_rag_utility(trail)
|
||||
|
||||
if utility_score > 0.7:
|
||||
# High utility → strong training signal
|
||||
training_examples.append({
|
||||
"query": trail.task_description,
|
||||
"rag_context": trail.rag_terms_used,
|
||||
"response": trail.solution,
|
||||
"weight": utility_score # RLVR reward weight
|
||||
})
|
||||
```
|
||||
|
||||
**This trains LoRAs to:**
|
||||
- **Mnemosyne (Memory)**: Recall accuracy vs phoebe ground truth
|
||||
- **Aletheia (Truth)**: Confidence calibration (was confidence boost justified?)
|
||||
- **Moira (Pattern)**: Which task patterns benefit from RAG vs pure reasoning

|

|
||||
### Quality Gates Prevent
|
||||
|
||||
1. **Garbage in RAG** - staging area catches malformed entries
|
||||
2. **Topology corruption** - DriftProbe-lite policies block dangerous terms
|
||||
3. **Useless bloat** - utility policies remove low-value entries
|
||||
4. **Premature training** - only high-utility terms get flagged
|
||||
5. **Hidden knowledge waste** - track what's available but never used (curriculum gap)
|
||||
|
||||
### Policy Evolution Triggers
|
||||
|
||||
As Young Nyx grows, unlock stricter policies:
|
||||
|
||||
| Trigger | New Policy Unlocked |
|
||||
|---------|---------------------|
|
||||
| 100 successful RAG retrievals | Semantic quality checks |
|
||||
| First LoRA training run | Topology safety (DriftProbe-lite) |
|
||||
| 1000 decision_trails logged | Utility validation (help rate > 60%) |
|
||||
| First INTERNALIZED term | Cross-reference consistency |
|
||||
| 10 INTERNALIZED terms | Cost-effectiveness (ROI > threshold) |
|
||||
|
||||
**Progressive difficulty**: The bar for entering RAG rises as Young Nyx becomes more capable. Early: anything valid. Later: must prove utility.
|
||||
